reserved pages\n\nThis patch introduces struct rq_map_data to enable bio_copy_use_iov()\nuse reserved pages.\n\nCurrently, bio_copy_user_iov allocates bounce pages but\ndrivers/scsi/sg.c wants to allocate pages by itself and use\nthem. struct rq_map_data can be used to pass allocated pages to\nbio_copy_user_iov.\n\nThe current users of bio_copy_user_iov simply passes NULL (they don\u0027t\nwant to use pre-allocated pages).\n\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Jens Axboe \u003cjens.axboe@oracle.com\u003e\nCc: Douglas Gilbert
